Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494076, here are decompositions:

23 + 31494053 = 31494076
149 + 31493927 = 31494076
167 + 31493909 = 31494076
293 + 31493783 = 31494076
359 + 31493717 = 31494076
503 + 31493573 = 31494076
557 + 31493519 = 31494076
563 + 31493513 = 31494076

Showing the first eight; more decompositions exist.
